摘要
利用在集合上定义映射和Knaster不动点原理,讨论了奇数阶中立型差分方程有界正解的存在性,得出了相应方程有界正解存在的充要条件.
The existence of a bounded positive solution for odd neutral difference equations is investigated by Knoaster fixed-point theorem and definition of the compressed injection on a set.A sufficient and necessary condition for existence of a bounded positive solution about the corresponding equation is obtained.
